High-quality sealants must possess two core characteristics: low viscosity and strong adhesion. Low viscosity effectively extends application time and reduces material waste; excellent adhesion ensures tight bonding to the substrate surface, significantly improving sealing and fixing effects.
Many people are unclear about the actual use of thermal paste. It primarily fills the tiny gaps between heat dissipation devices and heat-generating chips, sealing the contact surfaces and significantly improving heat conduction efficiency. This allows heat dissipation components to fully utilize their heat dissipation capabilities, contributing to stable heat dissipation of electronic components.
For high-power components, using electronic potting compounds is not optional, but a crucial prerequisite for ensuring their stable operation. Air has a thermal conductivity of only 0.024 W/(m·K), resulting in extremely poor heat dissipation. If high-power components rely solely on natural air cooling, heat cannot be effectively conducted away, easily leading to localized high temperatures. This high-temperature environment directly damages components and related parts, significantly reducing the reliability of the entire electronic system and shortening its normal operating life. Therefore, the appropriate selection of electronic potting compounds is essential for the stable operation of high-power components.
In the application process of silicone potting compounds, degassing is a crucial step in ensuring product quality. Its core purpose is to ensure that the cured compound is free of air bubbles and pores, both internally and on the surface, thus avoiding impacts on the subsequent performance of the product. Many users believe that degassing simply requires opening a vacuum chamber for extraction; however, improper operation of this step can lead to a series of problems. This article will detail the consequences of degassing abnormalities, the key factors affecting degassing effectiveness, and preventative measures.
The performance of electronic encapsulation AB glue hinges on correct pouring operations and scientific curing techniques. Improper operation not only wastes materials but also severely impacts its core protective properties such as insulation, waterproofing, and shockproofing. Therefore, operators must master relevant practical skills to ensure the adhesive functions effectively.
Silicone potting compounds are important protective materials for electronic devices, effectively providing waterproofing, moisture resistance, dustproofing, insulation, thermal conductivity, and corrosion protection, ensuring the stability and lifespan of electronic devices. Their curing methods are mainly divided into room temperature curing and heated curing. In practical applications, if abnormal curing occurs (such as incomplete curing, slow curing speed, or no curing at all), it is mainly caused by the following three core factors:
